I agree, in our experience the unofficial on campus visits were always the best. Remember, the NCAA rules for what contact can and cannot happen vary by the calendar and by division. But the rules (and penalties) apply to coaches
not the players! So if the coach is setting up the meeting, don't worry about it.
Here's a link to the
NCAA Guide that will answer many questions. Starting on page 27 you will find the recruiting guidelines. Also, on page 19 are some good sample questions to ask.
